JAMES MCCLElhTiAlQDTQFQARSON orrr, MICHIGAN. I I 7' a ;WHI FFLETREE-HOO'K. H I i Be it known that 1, JAMES MCCL'ELLAV'ND, a

citizen of theUnited States, residing at Car the county of. Montcalm andState of'Michigan, have invented a new-and son City, in

useful -Whiflletree-Hook; andl .dohereby exact description,

declare the following to be a full, clear, and

the" invention, such as v will enable others skilledin the art to whichit appertains to make and use the same.

This invention relates to hooks adapted to be fitted to the end of aswingletree; and the object of the inventionisto provide a simple andinexpensive meanswhereby the. ring of the trace may very easily beattached to or detached from thehook.

More especially, hollow cup-shaped casting which is adapted to be fittedto the end of a swingletree' by cutting away the end of the latter andforming a shoulder against which the hollow cupshaped casting is adaptedto abut; "Furthermore, the casting 'is provided with a bead, andprojecting therefrom' is a two-pieced hook. j

v The invention consists in various details of construction and incombinations and arrangements of parts, which will be hereinafter fullydescribed and then specifically de fined in the appended claim." i V Myinvention is illustrated in the accompanying drawings, which, with thefigures of reference marked thereon, formapart of this application, suchfigures of reference indicat ing like parts in the views, in which i sFigure lflis a perspective-view of .the end of a swingletree withmyimproved hook fastened thereon. Fig. 2 is a similar view showing thehook in open position. Fig; 3 is a.

section on line 3 '3 of lug-1, and Fig. 4 is a the end of theswingletree. y a I Reference now being hadto the details of the,drawings by figures, 1 designates a swinletree the end of which is cutaway, as at 2, orming a shoulder 3 andleaving a contracted portion 4,which is adapted'to' be inserted in the hollow cup-shaped casting 5,said cast ocated 0n the circumference of the cast? ingbeing heldthereonby screws6.

Specification of Letters Patent. Application filed Apri1 5, 1905. Serialno. 253,956.

the invention provides a what I claim as new,

Patented Jan. 1, 1907.

' j ing a bead 7, and projecting from oneend of said bead is the rigidjaw 8 .of the hook, said jaw having .a shoulder, as at 9, and asemicircular portion 10. Said semicircular portion 10 is provided attheend with a projecting lug 11, which is provided for the urpose ofpreventing the ring of the trace fibm slipping therefrom. The other end.of the bead is cut away close to said end,"which cut- 1 away portionforms a recess 12, the sides of which have'apertures 13, adapted toreceive the pivot-pin 14. Pivotally mountedupon said pin .s the straightportion'of the movable j &W"15,' tl16 under side of which is fiattened,as at 16, to correspond with the flattenedsurface 17 of the rigid jaw 8.Thus it will be seen that when the two jaws are closed thehook will havethe appearance'of being circular in cross-section. j At the terminationof the flattened portion 16 of the movable jaw is a shoulder 18, whichis adapted to engage with the end of the semicircular portion ofthe'rigid jaw.

Projecting from the upper side of the movable jaw is a lug 19,corresponding to the lug 11 upon the rigid jaw, said lug 19 alsopreventing the ring of the trace from accidental displacement. Themovable jaw 15 is also provided with a semicircular portion 20 tocorrespond with the rigid jaw 8. The rigid jaw at the semicircularportion when casted is made a little larger in diameter, as at 21, asshown clearly in Fig. 3, this being for the urpose of allowing the ringof the trace to liave a bearing therewith without in any way coming intocontact with the upper portion of the movable jaw. Thus by reference tothe difierent figures of the drawings the detailed construction andoperation of the device will be clearly understood. 1

. Of course it is distinctly understood that various changesin thedetailed construction and operation of the device can be readily madewithout in any way departing from the spirit and scope of the invention.

Having thus fully described my invention, and desire to secure byLetters Patent, is

A whiflletree hook,

comprising a cupshaped casting,

a jaw formed integral therewith, and having a curved outer portion, a,In testimony whereof I have hereto afpivotedjaw alsohaving a curvedouter por fixed my signature in the presen'oe of two wittion overlappingsaid integral jaw, a recess I nesses.
